Write to NTFS-formated drives on Yosemite

I sometimes need to mount USB drives that are NTFS formatted and write to them. On Mavericks I achieved this using the Homebrew formula ntfs-3g which depends on osxfuse. After upgrading to Yosemite, osxfuse is broken. Homebrew message: ==> Upgrading osxfuse osxfuse: OS X Mavericks or older is required for this package. OS X Yosemite introduced a strict unsigned kext ban which breaks this package. You should remove this package from your system and attempt to find upstream binaries to use instead. Error: An unsatisfied requirement failed this build. I take this to mean that the kernel extension used by osxfuse is completely disallowed in Yosemite because it is not digitally signed by Apple, whereas in Mavericks it was allowed. So, is there any way now to mount and write to an NTFS-formatted USB drive in Yosemite using either open-source software or free, unencumbered (not spyware/malware or bundled with useless toolbars etc.) software from the App Store?
